Why don't my clean URL's work in Drupal, even though rewrite_module is present? - linux

Question

Hey guys. I'm asking this question here as a last resort, since I've been trying to solve the issue for almost two days now.
I'm trying to enable clean URL's on my Drupal web application. I have visited several public questions such as this one, but to no avail. My sincerest apologies if this is thus a repost.
Some (relevant) context:
The project involves automatically setting up a VM using a Vagrant script.
The VM has no GUI.
Vagrant uses VirtualBox.
Vagrant uses bento/centos-7.9 as a base box.
I use WSL on my physical device whenever I need a terminal for PS or Linux commands.
I'm setting up a LAMP stack on the VM using the following:
CentOS 7.9, as mentioned up above.
Apache 2.4.6, as in:
yum -y install httpd
MariaDB 10.5.9, as in:
wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup
chmod +x mariadb_repo_setup
./mariadb_repo_setup
yum -y install mariadb-server
PHP 7.4.16, as in:
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum-config-manager --enable remi-php74
yum -y install php php-mysql
I'm storing the extracted contents of Drupal (index.php, update.php,
core, sites ...) under /var/www/drupal/. I have given Apache
recursive ownership of that folder as to not create a hassle having to set up permissions. It's not a production project anyway.
In the /etc/httpd/conf/httpd.conf file, I have only touched the
DocumentRoot, which I set to DocumentRoot "/var/www/drupal". I do not want to use .htaccess.
When I run httpd -M | grep rewrite, I receive the output rewrite_module (shared). When I run phpinfo(); on a test page, mod_rewrite is present among the loaded modules.
Running the application, everything goes fine, and the following output is produced:
Drupal warnings top part
Drupal warnings bottom part
I'm aware of the other two warnings, but those are a worry for another day. When I continue despite the warnings, Apache loads index.php just fine:

However, the moment I click any button, this happens:
Screenshot of yet another problem
I suspect this is a consequence of the clean URL's not being enabled. However, as far as I know, all necessary modules have been installed.
What I have tried so far:
In /etc/httpd/conf/httpd.conf, trying everything that's suggested here.
In /etc/httpd/conf/httpd.conf, setting every AllowOverride option to All.
Checking for compability issues.
Moving the document root around.
Much more...
Help would be greatly appreciated. Many thanks in advance. If you require any more information, I will respond as soon as possible.

Hey guys. The issue has been solved.
Somehow, it suddenly works. I am now able to navigate the website without a Not Found error popping up.
I retried a method that didn't work before, but now it does. There was no change in any other variables. I edited /etc/httpd/conf/httpd.conf. Besides already having changed DocumentRoot to /var/www/drupal, I also added another piece of configuration right under that:
<Directory "/var/www/drupal">
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^ index.php [L]
</Directory>
I obtained this information from here.
The CLEAN URLS warning is still present though:
Drupal warnings top part
But there seems to be no problem when continuing despite the warnings. In fact, in the application itself, navigating to the errors/warnings section, the CLEAN URLS warning isn't even there!
